Application filed January 30- 1905-. Serial No. 243.342.

Be it known that I, FRANK B. 0001:, a-citizen ofthe United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Wire-Rope Clamps, of which reference being had-to. the accompanying drawings, illustrating same.

My invention relates to clamps used for clamping stranded ro s, cables, or thelike, therein, my rincipa object being to provide such a 0 amp which has a great holding power on the ropes, cables, or the like, and which is simple In construction,

In the accompanying drawings, Figure 1 the clamp of my invention, with two stranded conductors therein;

' tend. The

Fig. 2 is a' bottom vlew of the clamp; Fig. 3 is a top view of the clamp, with the stranded conductors shown in dotted lines; Fig. 4 is a cross-sectional view of the clam taken on line y 'y of Fig. 2, with portions s own in elevation, and Fig. 5 is a cross-sectional view of the clamp, taken on line w w of Fig. 2.

Likechara'cters refer to like parts in the several figures.

The body portion a of the clamp is preferably oval in plan and is provided with holes 0 c therethrou h, throughwhieh the threaded portions h h 0' ortion a is also provided with ribs or longitudinal side projections e e on each side thereof, which are cut away to form a transverse groove, as shown in Fig. 1, in which the stranded'cables or ropes d d are clamped. This transverse groove is not uite-as wide as the sum of the diameters of t e two ropes, so that when the latter are pressed'into the groove, they are also clamped together. The center of the top portion of a, is cut away as at f, so that when the nuts 9 g are tightened up, the ropes d (1 will be bent over the portions e e and drawn down into the hollow portionf, by the U-shaped bolt 7), as shown in dotted lines in Fig. 5. This clamps the ropes in place so as to give a great holding power against slipping. The

corners of'e e are-preferably rounded off to prevent themirom cutting into the ropes.

\Nhen-the nuts 9 g are tightened up, the

ropes or'cables 3 d are clamped together, are

squeezed into the transverse groove or channel 1n ribs 0 e, are each clamped by and bethe U-bolt or yoke b freely 6X tween the ribs e e and the boltor yoke b, and
